Plain-language summary
This 2-part, Phase 1, open-label study will determine the recommended Phase 2 dose (RP2D) of ARX788 in subjects with advanced HER2 positive cancers and will assess the safety and anticancer activity in breast, gastric and other advanced HER2 positive solid tumors.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age \>18 years
* Life expectancy \>3 months.
* Female or male subjects whose advanced HER2 expressing cancer has failed standard of care treatments, or for whom such therapy is not acceptable to the subject. Subjects with advanced breast, gastric cancer, or other solid tumor who test positive for HER2 by ASCO/CAP criteria (either IHC or FISH) must have received prior treatment with a trastuzumab containing therapy. Subjects who have been previously treated with pertuzumab, TDM-1, lapatinib, or other available and accessible HER2-directed therapies or investigational therapies are eligible.
* Disease measurability:
* Phase 1a: measurable or non-measurable disease per RECIST v 1.1.
* Phase 1b: measurable disease per RECIST v 1.1 (subjects with non-measurable disease are not eligible for Phase 1b).
* Histopathologic evidence of cancer based upon pathology report.
* Tumor tissue local laboratory HER2 testing results, adequate tumor sample available for confirmation of HER2 status. Subjects with other types of cancer must have previously tested locally for HER2 status by HER2 IHC or ISH assay.
* Phase 1a: ISH positive or IHC 3+ advanced cancer (including breast or gastric/esophageal or other solid tumors).
* Phase 1b: Cohort 8 advanced breast cancer (IHC 3+ or IHC 2+/ISH); Cohort 9 advanced breast cancer (IHC 2+ / ISH-); Cohort 10 advanced gastric cancer (IHC 3+ or IHC 2+/ISH+) or gastroesophageal junction adenocarcinoma; Cohort 11 other advanced s…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Number of subjects experiencing adverse events, frequency and seriousness of treatment emergent adverse events (TEAEs)
Timeframe: Day 1 through 30 days after last dose
2
Phase 1b: Objective response rate (ORR: complete response + partial response) per imaging assessment based on RECIST version 1.1.
